Whenever I use an edge finder and have to move the axis half the diameter, I like to put the center drill in the chuck first (before I move the requires offset distance of 0.375"). This lets me bring the point of the drill bit down to the edge of the work to confirm that I'm actually on the edge instead of accidentally one hand-wheel turn off. This is probably more useful of you don't have a DRO, although if your eyes are glued to the DRO, you can accidentally turn the hand-wheel in the opposite direction and still arrive at the same 0.25" reading. Depending on which edge you are finding you would be looking for a positive or negative number and it's not always intuitive because you have to think about which way the DRO is counting and if you're thinking about moving the work vs. moving the spindle.
First video I've found of yours, been following on Instagram for ages, always very interesting and such good explanation!
